Materials analyzed in 2019 - 2020

From Wiki

Round Robin testing of materials by the Materials Working Group

The goal of this work, conducted by members of AIC's Materials Working Group (MWG) Testing & Standards group starting in 2018, was to analyze a series of materials at several museums to see if a consistent result could be achieved at every location. The reason for the goal is to make sure every workplace can follow the same guidelines and obtain the same result.

The materials tested in the 2019 and 2020 Round Robins

  • Buffered paper: University Products Perma/Cor E-Flute corrugated board 612-00180E

  • Additional materials as needed for individual tests to act as controls
  • pH tests: acidic, neutral, alkaline, newsprint, and archival papers
  • Sulfur test: wool fibers (positive); cotton fibers (negative)
  • Chlorine test: PVC film (positive); Mylar polyester film (negative)
